pipe coiled exchanger
(OP)
I am trying to understand how many 1.25" pipe turns I can install in the 20" dia vessel. How small a coil can 1.25 sch 80 pipe be turned. I want to add a heating coil to the bottom of 20 " vessel and I wasn't sure how small I could get for the needed surface area.

You could probably get more area in the same gross volume by using the pipe as axial headers, with right angle connections to multiple spirals bent from small diameter tube, or with multiple embossed plate coils.

Horizontal, I would also consider putting a couple straight legths tied together with some 180 deg Ubends on the ends. It would be a whole lot cheaper IMO as long as you get the area required. You won't get as much turbulance but you could easily put it through a man-way and weld in place.
